I was unsure of this one at first, because I'd never heard of anyone in the cast except Kim Woo Bin. And I didn't think the lead men were particularly handsome, either. But, because it was written by the brilliant writer of Descendants of the Sun and many other great and popular dramas, I decided to give it a shot. Honestly, I thought it was brilliant. Witty, engrossing, screamingly funny, romantic, well acted, and very moving. Can't really think of many I liked better than this, and will definitely watch it again with my bestie in a month or two. By the end of this drama, I was in love with this whole very talented cast, and grew to think all of the lead males were adorable. I just can't gush enough, really, but I will spare you and stop now. Except to say that if you're on the fence, WATCH IT. Bet you'll binge it all in a few days. It took me less than four, and I lost some sleep over it.
